The evidence

• “During the irregular hostilities which followed that first attack of May 14 Black Hawk's various bands, including some scalping parties of Winnebagoes and Pottawatomies, made several raids on the Avhites of northern Illinois, resulting in the loss of many lives and producing widespread terror and panic among the settlers. The most notable instance occurred May 21, 1832. Thirty Pottawatomies and three Sacs under Girty surprised and slaughtered fifteen men, women and children at the Davis farm on Indian creek, twelve miles north of Ottawa.”
